Omar, 21, was sleeping when the first rocket hit. His mother, panicking, came running into his room.

"My mom woke me up saying, 'Stand up immediately.' She said Abdulrahman went out and the plane is roaming, is circulating above, you need to get him back to the house," Omar tells us.

He was too late.

"I kept running, the first guy saw Abdulrahman injured and he said 'Catch up to your brother, he's about to die.' I can't control, I ran, ran, ran. When I got there, they told me the ambulance has just taken him."

Omar found his brother in the makeshift field clinic, in the basement of the town's mosque.

"Once he saw me, he shouted 'Omar!' -- shouted with all his strength. I didn't see what happened, I just saw blood. When I got closer I saw his leg and I just yelled and I started crying."

Abdulrahman's leg was amputated; there was no way to save it. It was practically entirely severed just below the knee.

"After he woke up I was crying, I couldn't control myself, and he said, 'If you love me don't cry,'" Omar recalls, eyes slightly widening, acknowledging our amazement at his brother's strength. He says Abdulrahman made him promise not to cry in front of their mother.

"I said I will control myself," Omar continues. "I told him, do you know where your leg is? He said, 'I know it's cut, I keep feeling it, it hurts.' I told him it just went before you to heaven."

And that is also when Omar made another promise to his younger brother: that he would walk again.

Omar started working to save money for a prosthetic, but quickly realized that it would take too long to raise the funds. He began asking around, went online. A group of Egyptian doctors happened to be visiting the field clinic, and they told him about the Global Medical Relief Fund, a small U.S. nongovernmental organization that is dedicated to helping children badly wounded in disasters and war zones. GMRF takes care of children's follow-up prosthetics and physical therapy until they reach the age of 21.

The founder, Elissa Montanti, quickly responded: Yes, of course, she would take on his case, but first the brothers had to get to Turkey.

They did make it safely across the border. And after a long and arduous journey navigating a country they don't know, a language they don't speak and with meager funds, they made it to Ankara, the Turkish capital, where they are now waiting.

Montanti has been working on the brothers' paperwork to get Abdulrahman to the U.S. for medical treatment, made all the more challenging because they don't have passports.

Their visa requests were denied. Now they are waiting to see if the State Department will grant them humanitarian parole.

Omar pulls his brother in closer, gently stroking his cheek. The two, always close, are now inseparable.

But Abdulrahman, despite his frequent shy smiles, is constantly plagued by the memories.

"He has nightmares and sometimes daydreams, bad daydreams," Omar tells us. "He says 'I feel it, I feel just like there is a snake around.' I keep telling him it doesn't exist and he says it hurts and starts screaming."

Abdulrahman, under his breath, says he sees a big one, surrounded by smaller ones.

"All the time I think how to make him comfortable. It's just like raising a child -- I have to take all the responsibilities. He needs to be educated again. I want to take advantage of this situation to teach him languages, everything I can."

Tragically, Abdulrahman has already learned one of the harshest lessons of all.

"The most important thing that he's learning at this time," Omar says, "it's to be aware, to grow up his mind. He's not a child anymore."
